GE Aviation and Etihad Airways have partnered to launch GE’s 360 Foam Wash, a jet engine cleaning system, to optimize the performance of Etihad’s GE90 and GEnx-1B engines on its Boeing 777 and 787 fleets.
Working with Etihad as a launch partner for the Etihad Greenliner program to innovate, develop and test aviation decarbonization technologies, GE has awarded Etihad technical licenses to use GE’s patented 360 Foam Wash system on its GE90 and GEnx-1B aircraft engines. The licenses allow Etihad Airways to perform the engine foam wash on its fleet of 777 and 787 aircraft completely in-house.
GE’s 360 Foam Wash is an alternative to the water wash method, and restores engine performance leading to reductions in fuel consumption. The process involves injecting a specially-formulated, proprietary solution that removes dust and dirt particles in the engine. The system is self-contained, allowing it to be used inside maintenance hangars or outdoors.
Etihad is the first airline to trial GE’s Foam Wash with a GE90 engine on wing, receive a GE90 Foam Wash license, and receive licenses for multiple GE engine programs (GE90 and GEnx).
“GE Aviation shares a commitment to develop innovative solutions in aircraft engine maintenance with the team at Etihad Airways,” said Jean Lydon-Rodgers, vice president and general manager of GE Aviation’s After Market Strategic Solutions. “We are learning more about how our engines operate and how they respond in hot and harsh environments than ever before, and our longstanding relationship with Etihad has been integral to that process.”
During technology trials with its GE90 and GEnx engines, the foam wash solution allowed Etihad to improve engine performance by reducing the build-up of deposits in the engine, lowering engine exhaust temperatures, and improving engine compressor efficiency. These improvements led to reduced fuel consumption and increased engine time on wing.
“Our partnership with GE through the Etihad Greenliner programme is a prime example of industry collaboration that will have a significant impact on Etihad’s efficiencies and provide a case study for the broader industry,” said Paul Kear, senior vice president technical, Etihad Airways. “Through 2021 alone, we expect to realise significant fuel savings and a reduction of more than 7,000 metric tonnes of CO2 for the combined GEnx-1B and GE90 engine fleets, compared to water wash methods.”
Through the Greenliner program, Etihad collaborates with industry leaders including Boeing and GE in an “eco partnership,” spearheaded by a specially-themed Boeing 787 Dreamliner powered by GEnx engines to test products, procedures and initiatives designed to reduce aircraft carbon emissions on its fleet of 787s.
